Understanding the operating principle of a wheeled crane

Widely used in various construction sites and projects across many industries, the flexibility and outstanding performance of wheeled cranes are undeniable. But have you ever wondered how a wheeled crane operates? The article below will help you understand more about this.

Operating Principle

A wheeled crane operates based on a combination of a hydraulic system and a control system. To operate the machine, the operator needs to control the crane arm. At this point, the hydraulic system provides the power needed to lift, rotate, and move the arm.

Meanwhile, the control system monitors the crane’s operations and ensures safety during its use. The detailed operating principles are as follows:

• Lifting and lowering: When the operator raises the crane arm, hydraulic oil is pumped into the hydraulic cylinders, causing the arm to lift. When hydraulic oil is released, the arm lowers.
• Rotation: Hydraulic oil is pumped into the crane’s rotary cylinder, causing the crane to rotate either clockwise or counterclockwise.
• Arm movement: Hydraulic oil is pumped into the crane’s movement cylinders, allowing the arm to extend or retract.

How It Works

Based on the above principles, the operator of a wheeled crane must also be able to calculate the load capacity of the crane, determine the weight of the cargo, and properly set up, position, and stabilize the crane before lifting. The crane operator is also responsible for assembling, disassembling, moving, and transporting the mobile crane, as well as participating in rigging procedures.

For smooth operation, it’s important to carry out regular maintenance and cleaning tasks for the crane, such as lubrication and cleaning—especially as these machines are used across many industrial fields.

In conclusion, the operating principle plays a major role in making the wheeled crane a powerful and versatile tool. Hopefully, the insights from Comacpro will help you use it safely and effectively.
